i Application filed December 11,1925. Serial No. 74,666.

This invention relates in general to improvements in the art of supporting and lubricatingv rotary elements, and relates more specifically to improvements in the construction of, mode of assembling and dismantling, and operation of, bearing and lubricating structures for rotary shafts or thelike. An object of the invention isto provide an improved hearing which is simpleand'compact in construction and efiicient 1n operation. Another object of the invention s to provide improved bearing. structure which may be conveniently constructed and read ily assembled and. dismantled. A further 1 object of the invention is to provide improved means for preventing escape 0f fluid such as "oil, from a bearin .or housing, without the aid of packing:- till another object of the invention is to provide improvements in bearing construction whereby the: cost oi manufactureis reduced to a minimum and the efliciency of operation of suchtdevicesis enhanced to a maximum. These'and: other objects and advantagesof the-invention will be apparent in the.course"of'the following description. 1 i I 1 A clear ponceptionof embodiments of the several novel features of they invention, and of the mode of assembling, dismantling and operating devicesconstructed in accordance therewith, may be had byreferringto the drawing accompanying and forming a part of this specification in which'like reference characters designate thevsame or similar parts in thevarious views.

Fig. 1 is axcentr'al verticalsectiontaken through the [improved Bbearing structure, taken .alongthe line 2-2 of Fig; 1 and looking in the direction of the arrows.

FIgi 3 1s a transverse vertical section through theiimproved bearing structure,

taken a-longthe line of Fig. 1 and looki ing in the direction of the arrows.

The improved'bearing structure specifi cally illustrated'in the drawing, comprises in general a one-piece housing4 associated with :a support. 26 in any suitable'manner and having a longitudinal tapered bore 18 therein; a bearing or sleeve member 5 -1o- "cated within the housing 4 and having an external tapered surface coacting with'the memberbore 18; a rotary shaft element 6 journaled in the bore 24 of the sleevemenr her 5 and extending throughan end opening 12 of thehousing 4; and a 'continuous or ring element 7 surrounding the shaft element 6 and disposed within a lateral :recess 16 formedin theupper portion of the bearing member 5. V y The housing/1 has an inwardly extending projection or mg 115 formed integral with and located within the upper portion of the housing, and'also has an opening lOlocated at one side of the lug and extendinglat erally toward the common axis of the bore 18 a removal of the ring element 7 therethrough,

the opening 10 being normally sealed by means of aclosure 11 which .isswingablyf supported from the hOusingA by means of a pivot 25. The housing 4 is divided into two end chambers 20,21 and anintermediate chamber 17 by means of transversewalls Within which the housing bore 18 is formed, the latter chamber'17 havingan oil well in the lower portion thereof and communicating with the end chambers 20, 21through oil 1 return openings 22, 23 respectively, formed 1n thetransverse walls. y Located within the end chamber and formed integralwith the housing 4, is an inwardly extending; projection or" lug 13.

The bearing 01' sleeve member 5 hasan end recess 14 formed to receive the housing lug. 13' and to lock the sleevemember5 against rotation a-fter thismember hasbee'n inserted endwise-intothe bore 18 of the housing il An annular groove or recess 9 formed in the t 95 housing 4, completely surrounds the end" housing opening 12 within the end chamber 21. Associatedwith the shaft element G'Iand 1 located between the end of the bearing ele ment 5 and the groove 9, is an annularbil thrower 8 which has a maximum diameter loo less than the internal diameter of the hous-i ing opening 12. .As shown, the oil thrower .8' is formedintegral withthe shaft element 6 and has anend face cooperating with-the end of the sleeve member 5 to-retain the 1 member 5 within the housing bore 18., The sleeve member5 is provided with an internal groove 19 adjacentto theoil thrower 8 and communicating through a lower opening with the chamber 21.

' at the right of the lug 15, the sleeve members in order to assemble the hearin Y structure, it is first necessary to insert the rmgelement 7 into the medial chamber 17 of the housing 4 through the upper opening 10 at the left ofthe ringretaining lug 15 as viewed in Fig. lfandto shift the element 7 to theri'glit of the 111 15 within the housing. when the ring element 7 has been thus positioned 51 may be inserted through theend opening 12 of tl1 e, housing and passed through the ringele nent 7 untilthe element 7 drops into ,Aifter the ring element 7 has been so in tiat d, t e sle memb r 5 m y dri ten ,1 into i the tapered hore 18 a of. the; housmg tbymseee e fihe e em t 6, n l h lateral ifecess lti .is disposed directly beneath the lug 15, and the end recess ltengages the lug lii to positively preventrotation of the ineiuher within the housing d. \Vith the p art s thus co i' pletelyassembled, the ring element 7; e 1 w t Q ba n pre id lnft e lowerportionoi the housing chamber 17 eesl h llth 'e 'el' 8 oon r=i es th h end ofthe sleeyemginber 5 to positively prevent end vi se displacement 0t theineinber 5 within theho sing 4; i a 1 lhe norma gperation ,ofthe assembled entin s rewn? l$ as f 1lQW s aft elemen 6 during its rotation, causes the ring element 7 .to rotate ate relatively lower el ed end b lev e l. f om h b n at the bottom of the chamber The elevated il fiew'eif qnint ie mem r r es a o he beefing surfac -%t9 bot nds o thesleeve member 5, Y The oil delivered from he e def membe e nt t and ch ber ZQLgravitatesbacl; into the chamber 17' through the return ope ing 22, x vhile the oil delivered into the end chamhen21 from the grhove 19, likeyvise gravitates into the chame 7 t nb g the ret e1 en ng23= In case some ofth e oil flows beyond the groove 19 andthe"adjacentendof the sleeve memv beif' fig-"the revolvingfoil thrower auton atis,

such oil eventually granites into and along thea'nnular groove 9 andis deposited ithin the lower. portion ofthefichamber 21 without coming in contact with the shaft element 6. Theo lis thus effectively prevented from st lp fig romthe i ieg lirb ghth 7 bore 12,'by the oil throvy'en8 and the annular Lecess 2 ithout necessitating theuse of in leme t th p n 12-" orde rto idisma nile the bearing structure, is desirable toinitially dna v oil the Oil liyremoving the plug at "the hottoin, of

When the shaft element (3 liasbeen removed, the sleeve member '5 'in'ay be driven fr on; within the bore 18 until the lateral recess"l6 has as sumed a position to the right of the retain hg lugla'z asviewedin-Fig. 1. The ring element 7 may then be removed from the recesslG in any convenient'manner, where upon t-he sleeve member 5 may be completely \vitl1d1'a\vn.;f1'o1n. the bore 18 and from the housing t. through the end opening lfl. The removal ofthering element 7 from within the recess 16 may obviously be eifected by tipping the bearing-structure up-side down, or by so formingthe end recess 1% and leg 13 that the member 5 may be rotatedlSU degrees: after the lateral. recess-16 is. clear of the lug 15, or by chamlering the left side of the recess 16 so that the element 7 will be elevated out of gtlierecess by wedgingaction when the member 5 is shittedto the right and the element Tuengages: the wall atthe,

The'cooperating oil thrower 8 and recess 9 effectively prevent escape otuoil alongthe shaft element 6 while permitting formation of theopening -12 of'suificients ze to enable-free endwise insertion: and withdrawal of the element 6, thrower:8 and h1emher 5 therethrough; and such anassemhla e of -oil I escape, preventing elements may o 4 viously he applied at the opposite end ot the housing r l if desired. i s

It should be understoodthat it is not'd'esired to limit the invention either by the use of specific terms oriotherwise, *to the exactdetails of construction herein'shown and de scribed, forvariousmodifications within the scope of the claims skilled inthe art. a

It is claimed and desired to; secure by' Letters Patent i a 1.
